| With the rapid development of microelectronics, single chip microcomputer (MCU) is widely used in the fields of household electrical appliances, computer peripheral, communication, industrial control, automation of production, intelligent equipment and instrumentation because of its prominent merits such as fast operation speed, small volume, cheap price, strong expandability and so on. And it has become the most efficient tool for scientific research, teaching and industrial technology. Meanwhile, with the rapid development of the global semiconductor industry and technology, the integration of IC increases rapidly and its functions become more and more powerful. However, the price is getting lower and lower. All these make MP3 players very popular.The purpose of this research is using SPCE061A MCU, SPR4096 module,1602 LCD and wireless sending module to realize a simple carrier MP3 player which has a lot of control functions, for example, you can play, start, pause, stop a song and choose the previous or the next one with a friendly user interface. In addition, the balancing effect can be displayed in 1602 LCD when music is played and the volume can be controlled conveniently. In this paper, the theory was firstly discussed and investigated in details. And experiments were carried out and the satisfactory result was obtained. The truth of theory and rationality of design plan are analyzed and proved to be acceptable. At last, useful advice is given for the future study. |
